How to Use the Douyu MCP in Pydantic AI

Q: How do I initialize the Douyu MCP Server in Pydantic AI?

Use the unified MCPToolset class pointing to your Vinkius HTTP endpoint. This loads the MCP tools dynamically so you can pass them to your agent.

Q: What happens if Douyu returns unexpected user stats in Pydantic AI?

The framework raises a validation error immediately if getuserstats returns fields that violate the schema, preventing silent data corruption.

Q: Can my Pydantic AI agent search for Douyu streamers reliably?

Yes. The agent uses searchstreamers to locate accounts, and Pydantic AI ensures the returned list matches the strict search schema.

Q: How do I manage WebSocket parameters safely?

Call getdanmuconfig to get connection details. Pydantic AI validates the WebSocket IP and port formats before passing them to your connection logic.

Validate Douyu data with Pydantic AI

Live stream APIs can change without warning. By using `get_live_rooms` and `get_room_detail` inside this MCP framework, every room status and viewer count is strictly validated against Python types. If Douyu changes a response field, the toolset fails immediately. This prevents your agent from processing corrupt data or making decisions based on malformed JSON.

Type-safe gifting metrics via MCP Server

Parse financial metrics without silent failures. Your Pydantic AI agent calls `get_top_donators` and `get_gift_list` to track high-value interactions in live Douyu rooms. The Pydantic AI framework guarantees that every Douyu donation amount and gift ID matches your expected schema before the agent sees it.

Track users and send verified messages

Manage interaction safely. The Pydantic AI agent uses `get_user_stats` to verify viewer profiles and `send_message` to post to the live Douyu chat. Because the framework is model-agnostic, you can use these validated tools with any LLM while maintaining strict runtime guarantees.

Setup guide

Set up Douyu MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "douyu-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Douyu tools.",
)

result = await agent.run("List recent Douyu transactions")
print(result.output)
